CAR-WHEEL.

To all whom 'it may concern:

Be it known that LEoNARD P. SonTE, a citizen of the United States of America, residing at Louisville, in the county of J efferson and State of Kentucky, has invented certain new and useful Improvements in Car-Vheels, of which the following is a specification.

This invention relates to an improvement in wheel construction and is designed more particularly for use in connection with track guided cars and other wheeled vehicles using heavy wheels revolving. on a fixed axle or spindle.

One important object of the invention is to improve the general construction of the hub portion of such wheels.

A second important object of the invention is toprovide an improved hub cap arrangementfor wheels of this character.

A third important object of the invention is to provide an improved construction of built up hub wherein the inner end of the hub is formed separately from the body of the hub but wherein the spokes of the wheel coperate with said inner end to hold the same central of the hub.

With the above and other objects in view, the invention consists in general of certain novel details of construction and combina tions of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings7 like characters of reference indicate like parts in the several views, and

Figure 1 is a Side elevation of a wheel constructed in accordance with this invention.

Fig. 2 is a section on the line 2-2.of Fio. 1.

Ifig. 3 is a perspective detail showing onehalf of the improved hub cap used herewith.

Fig. 4 is a similar detail showing one-half of the detachable inner hub end used herewith.

In the embodiment of the invention herein illustrated there is disclosed a wheel provided with the usual flanged tire 10. This wheel has a centrally disposed hub 11 which is formed integral with the flange, with the flange and hub being connected by spokes 12. The inner edges of these spokes are cut away as at 13 to form shoulders and between these shoulders is fitted the flange 14 of an inner hub and including a hollow cylindrical body Specification of Letters Patent.

15 provided with an internal annular flange vide spacing for the outer end of the shafty 17. In the main hub 11 and hub cap 23 are provided complemental grooves 25 so arranged that when the hub cap is in position these grooves form a semi-circle in cross section, a similar semi-circular Groove 26 being formed in the shaft 17 in order that retaining balls 27 may be held in these grooves and prevent the wheel moving longitudinally of the shaft. In the main hub 1,1 is also?` formed an annular groove 28 and on the Patented Dec. 13, 1921. y

face of the hub cap 23 is an annular tongue or ange 29 which, when the hub cap is in place, fits in the groove 28. It is preferred that the hub body 11 and hub end 15 be of suliicient internal diameter to accommodate a roller bearing 30 which is held in position by the inwardly extending' portion 31 of the main hub 11 and by the flange 16 of the inner hub end. In this way the roller bearing is thoroughly protected from dust or the like since the inner end is protected by the dust packing 19 while the outer end is protected both by the inwardly extending por-- tion 31 of the hub and by the hub cap, the tongue and grove arrangement of said cap preventing any dust or dirt working in. For lubrication purposes the hub cap is provided with the usual tapped opening 32 for the reception of an oil cup or a grease cup and the hub body is provided with an annular channel 33 around the roller bearing. From this channel leads a passage 34 normally closed by a plug 35, the passage forming a filling opening so that lubricant can be injected into the channel 33 by removing the plug 35 and injecting the same through the passage 34.

There has thus been provided a simple and efficient device of the kind described and for the purposes specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact ther provided with an internal annular form herein shown and described, but it is groove intermediate its ends and having wished to include all such as properly come port communications with the exterior of within the scope claimed. s the hub body, an inner hub end secured to Having thus described the invention, what said hub body and having an inwardly eX- is claimed as new, is tending fiange atts inner end, a shaft pass- 1.
